Thanks Mario - I appreciate the guidance! Uff... I see I left a clause dangling in my last sentence there! Oops!
Anyhow, since I posted, I happened to come across the idea of using a one pole filter to smooth the signal and was able to implement something... and then later refine the implementation with the help of colleagues who have more DSP knowledge than I do. I've got something working fairly well, but will certainly see what this paper has to offer... I'm sure there's plenty of room for improvement. сб, 29 февр. 2020 г. в 19:30, Mario Buoninfante <mario.buoninfa...@gmail.com >: > Hi Andrew, > > It seems to me you need an envelope follower. > You can find more info about a possible implementation here: > https://www.bbc.co.uk/rd/publications/rdreport_1983_17 > > It's about dynamic range control (compressor, expander, limiter, gate), > and all of them use an envelope follower. > In alternative, you could start from here as well: > https://chuck.cs.princeton.edu/doc/examples/deep/follower.ck > > Cheers, > Mario > > On Tue, 25 Feb 2020 at 02:38, Andrew Telichan Phillips < > a.telichanphill...@gmail.com> wrote: > >> Hello, >> >> I'm wanting to capture the amplitude envelope from a live source and >> generate feedback loops...
